A certain telescope has an objective mirror with an aperture diameter of 200 mm and a focal length of 2 000 mm. It captures the image of a nebula on photographic film at its prime focus with an exposure time of 1.50 min. To produce the same light energy per unit area on the film, what is the required exposure time to photograph the same nebula with a smaller telescope that has an objective with a 60.0-mm diameter and a 900-mm focal length?

- Two stars that are 109km apart are viewed by a telescope and found to be separated by an angle of 105 radians. If the eyepiece of the telescope has a focal length of 1.5 cm and the objective has a focal length of 3 meters, how far away are the stars from the observer?arrow_forwardA large reflecting telescope has an objective mirror with a 10.0-rn radius of curvature. What angular magnification does it produce when a 3.00 m-focal length eyepiece is used?arrow_forwardYou need to record an image on a flat array of CCDs (charge coupled devices—basically a detector). You have two convex lenses mounted in a tube to which you will also attach the CCD plane. The first lens has a focal length of 15 mm and is positioned 25 mm from the sample to be imaged. The second lens, with a focal length of 10 mm, is closer to the CCDs and is 50mm from the first lens. How far away from the second lens will you mount the CCD plane? You must solve this problem using a good diagram and geometry. It is not permissible to use the lens/mirror equation, except to check your answer.
